In this paper we prove the existence of an infinite number of radial solutions of 8e676f68811b2e1" title="Click to view the MathML source">Δu+K(r)f(u)=0 on the exterior of the ball of radius R centered at the origin in 9e8aadf101da4847ace01df320f3731e" title="Click to view the MathML source">RN such that with prescribed number of zeros where 9d9b2f03042ad8c49767bc6e64473b" title="Click to view the MathML source">f:R→R is odd and there exists a β>0 with 99c7c7284fe8cd409aa19b" title="Click to view the MathML source">f<0 on 9ec4da5" title="Click to view the MathML source">(0,β), 9318e67a493cf1197d807c986" title="Click to view the MathML source">f>0 on e60e152b9087654428a30e310b9225d" title="Click to view the MathML source">(β,∞) with f superlinear for large u , and K(r)∼r−α with 0<α<N.
